Re: [PSUBS-MAILIST] Amazing photograph...

If the 300M tons were a misstatement, and the actual mass were 300M lbs
instead, that would be 150K tons, which would be 2300+ cu ft submerged.  Such a
berg might draft 30-ish feet.  It might stand 10' high at the peak, above
water.  It might be possible to get such a picture, based on the below, iff
everything was just exactly perfect and several images were photographed at
different depths and then merged ("stitched") together electronically (such
software is common these days, if you look for it).  

That's going some to "save" the picture!  You'd need a "perfect" photo above
water and one or more below, you'd need Carribean-clear water in the North
Atlantic, you'd need a brilliant day with no wind to speak of (note the calm
surface), you'd need a helluva camera with a rock-steady platform above and
below, you'd need either amazing luck or the patience and talent of Ansel
Adams, and then you'd need to process the whole thing electronically to stitch
the images together.  And, did I forget to mention, you'd need to overstate the
size of the berg by a factor of 2000?

Ya know, I once saw a movie where a droid projected a hologram of a princess
asking for help from a Jedi master who might really be a manifestation of The
Force.  I wonder if they faked it?
